Image display method, information processing apparatus, and recording medium having program recorded thereon

ABSTRACT

An image display method includes: acquiring a first image; acquiring a captured image obtained by imaging a projection receiving object of projection light; and displaying a setting image including a first region in which the first image is displayed, a second region in which the captured image is displayed, and a third region in which a preview image including at least a part of a deformed image obtained by deforming the first image according to an image of the projection receiving object included in the captured image is displayed.

The present application is based on, and claims priority from JP Application Serial Number 2022-055409, filed Mar. 30, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND 1. Technical Field

The present disclosure relates to an image display method, an information processing apparatus, and a recording medium having a program recorded thereon.

2. Related Art

A technique for deforming a shape of an image to be displayed into a desired shape has been developed. For example, JP-A-2021-158625 discloses an image display system that images a projection receiving object to be projected by projection light, and that prompts a user to execute an operation of setting a shape of a projection image to be projected onto the projection receiving object according to a shape of the projection receiving object recorded in a captured image. In the image display system, a captured image obtained by imaging the projection receiving object of the projection light, and an object (specifically, a square image) for setting a region occupied by a projection image projected onto the projection receiving object are displayed on a touch panel for the user to perform a setting operation. The user changes a position and a shape of the object according to the shape of the projection receiving object recorded in the captured image. The projection image is disposed on the projection receiving object according to the position and the shape of the object.

However, in the related-art image display system, since a projection image before changing the shape and a projection image after changing the shape are not simultaneously displayed, the user cannot directly compare the shapes of the projection images before and after the change. Therefore, it is difficult for the user to accurately check whether the projection image is appropriately deformed into a desired shape.

1. First Embodiment

In a first embodiment, an image display method, an information processing apparatus, and a program according to the present disclosure will be described by exemplifying a computer that causes a display device to display a setting image including an image before a shape is changed, a captured image obtained by imaging a projection receiving object of light projected from a projector, and a preview image including a part or all of an image whose shape is changed based on the captured image.

1.1. Overview of Computer

Hereinafter, an overview of a computer 1 according to the first embodiment will be described with reference to FIGS. 1 and 2 . FIG. 1 is a schematic diagram showing a state in which the projection receiving object of projection light is imaged. FIG. 2 is a schematic diagram showing a state in which a projection image GS is projected onto the projection receiving object of the projection light. In the embodiment, a torso 3 is the projection receiving object of light projected from a projector 7. The projector 7 displays the projection image GS by projecting the projection light onto a projection region RS of a wall surface W1 and the torso 3 disposed in front of the projection region RS.

A camera 5 acquires the captured image GP1 by imaging an imaging region RP of the wall surface W1, and the torso 3 disposed in front of the imaging region RP. The computer 1 causes a touch panel 16 provided in the computer 1 to display a setting image GC1 including the captured image GP1 that is acquired from the camera 5 fixed to a predetermined position and the image GG1 that is acquired from an external server (not shown). Further, the computer 1 deforms the image GG1 based on an operation from a user on the setting image GC1 displayed on the touch panel 16. The computer 1 causes the touch panel 16 to display a preview image GV including at least a part of the deformed image GG1. When the user checks the image GG1 and the preview image GV and determines that the image GG1 is appropriately deformed, the computer 1 outputs the deformed image GG1 to the projector 7 based on an operation from the user. The projector 7 displays the projection image GS including the deformed image GG1 by projecting projection light based on the deformed image GG1.

That is, the user can display the projection image GS according to a shape of the torso 3 by deforming the image GG1 according to the shape of the torso 3 recorded in the captured image GP1. Further, the user can check whether the image GG1 is appropriately deformed by comparing the image GG1 with the preview image GV including the deformed image GG1.

1.2. Display Method and Deformation Method for Image

FIG. 3 is an illustrative diagram showing the setting image GC1 a. The setting image GC1 a is an aspect of the setting image GC1.

The setting image GC1 includes a region R1, a region R2, and a region R3. Further, the setting image GC1 includes a button B1, a button B2, and a button B3. The image GG1 is displayed in the region R1. The captured image GP1 is displayed in the region R2. The preview image GV is displayed in the region R3.

The setting image GC1 a is the setting image GC1 first displayed on the touch panel 16 after the computer 1 acquires the image GG1 and the captured image GP1. In the setting image GC1 a, the image GG1 is displayed in the region R1, and the captured image GP1 is displayed in the region R2. In a state in which the setting image GC1 a is displayed on the touch panel 16, the user designates the one or more points DG on the image GG1 by touching the touch panel 16. The computer 1 receives an operation from the user who designates the one or more points DG on the image GG1. Further, the user designates the one or more points DP on the captured image GP1 by touching the touch panel 16. The computer 1 receives an operation from the user who designates the one or more points DP on the captured image GP1.

FIG. 4 is an illustrative diagram showing the setting image GC1 b. The setting image GC1 b is an aspect of the setting image GC1.

In a state in which the setting image GC1 a is displayed on the touch panel 16, the computer 1 changes the setting image GC1 to be displayed on the touch panel 16 from the setting image GC1 a to the setting image GC1 b by receiving an operation from the user who designates the points DG1 to DG21 on the image GG1 and an operation from the user who designates the points DP1 to DP21 on the captured image GP1. The setting image GC1 b is similar to the setting image GC1 a except that markers MG1 to MG21 are displayed in a manner of being superimposed on the image GG1 and markers MP1 to MP21 are displayed in a manner of being superimposed on the captured image GP1. In FIG. 4 , a point DPx is a point corresponding to a point DGx. Here, the value x represents an integer of one or more. For example, the point DP1 corresponds to the point DG1. Further, the point DP20 corresponds to the point DG20.

In the embodiment, the operation of designating the point DG20 on the image GG1 may be referred to as a “first operation”. Further, the operation of designating the point DP20 on the captured image GP1 may be referred to as a “second operation”.

The markers MG1 to MG21 for indicating positions of the points DG1 to DG21 are displayed in a manner of being superimposed on the image GG1 included in the setting image GC1 b. In FIG. 4 , a marker MGy corresponds to a point DGy. Here, the value y represents an integer of one or more. For example, the marker MG1 corresponds to the point DG1. Further, the marker MG20 corresponds to the point DG20. Further, the marker MGy includes a cross symbol indicating a position of the point DGy, and a number indicating the value y.

Further, the marker MP20 corresponds to the point DP20. Further, the marker MPz includes a cross symbol indicating a position of the point DPz and a number indicating the value z. The number indicating the value z included in the marker MPz is displayed in a predetermined range from the point DPz.

FIG. 5 is an illustrative diagram showing the setting image GC1 c. The setting image GC1 c is an aspect of the setting image GC1.

In a state in which the setting image GC1 b is displayed on the touch panel 16, the computer 1 changes the setting image GC1 to be displayed on the touch panel 16 from the setting image GC1 b to the setting image GC1 c by receiving an operation from the user who touches the button B1. The setting image GC1 c is similar to the setting image GC1 b except that the preview image GV1 is displayed in the region R3.

The button B1 is a button for the user to instruct the computer 1 to deform the image GG1. The user instructs the computer 1 to deform the image GG1 by touching the button B1 displayed on the touch panel 16. That is, the operation of touching the button B1 is an operation of instructing the deformation of the image GG1. The computer 1 deforms the image GG1 into the image GG2 by receiving an operation from the user who touches the button B1 on the setting image GC1 b. FIG. 6 is a schematic diagram showing the image GG2.

After generating the image GG2 by deforming the image GG1, the computer 1 generates the preview image GV1 by combining the image GG2 and the captured image GP1. The computer 1 displays the preview image GV1 in the region R3. When the image GG2 and the captured image GP1 are combined, the image GG2 may be transmitted at a predetermined transmittance, and the transmitted image GG2 may be displayed by being superimposed on the captured image GP1.

In the embodiment, the operation of instructing the deformation of the image GG1 by touching the button B1 may be referred to as a “fifth operation”.

Hereinafter, the deformation of the image GG1 will be described in detail with reference to FIGS. 7 and 8 . In the following description, the deformation of the image GG1 will be described by exemplifying a case in which the image GG1 is deformed into the image GG2. FIG. 7 is a schematic diagram showing a state in which the image GG1 is divided into a plurality of small regions. FIG. 8 is a schematic diagram showing a state in which the captured image GP1 is divided into a plurality of small regions. The image GG1 is divided into the plurality of small regions by a plurality of triangles formed by connecting the points DG1 to DG21 to one another using a plurality of line segments. Here, it is preferable that the plurality of line segments are connected in a manner of not intersecting with one another. Further, the captured image GP1 is divided into a plurality of small regions by a plurality of triangles formed by connecting the points DP1 to DP21 to one another using a plurality of line segments. Here, when a point among the points DG1 to DG21 is connected to another point among the points DG1 to DG21 in the image GG1, a point among the points DP1 to DP21 corresponding to the point among the points DG1 to DG21 is connected to another point among the points DP1 to DP21 corresponding to the other point among the points DG1 to DG21 in the captured image GP1. As a specific example, when the point DG17 is connected to the point DG20 in the image GG1, the point DP17 corresponding to the point DG17 is connected to the point DP20 corresponding to the point DG20 in the captured image GP1. That is, a one-to-one correspondence relationship is established between each of the plurality of triangles that divide the image GG1 and a corresponding one of the plurality of triangles that divide the captured image GP1. The computer 1 generates a plurality of conversion equations for deforming the image GG1 into the image GG2 based on the correspondence relationship between the points DG1 to DG21 and the points DP1 to DP21. Further, the computer 1 deforms the image GG1 into the image GG2 based on the conversion equations. The plurality of conversion equations are conversion equations for matching a shape of each of the plurality of triangles that divide the image GG1 and a shape of a corresponding one of the plurality of triangles that divide the captured image GP1 based on the correspondence relationship. As the conversion equation, for example, a conversion equation of affine conversion for converting the shape of each of the plurality of triangles that divide the image GG1 into the shape of a corresponding one of the plurality of triangles that divide the captured image GP1 may be used. FIG. 9 is an illustrative diagram showing the setting image GC1 d. The setting image GC1 d is an aspect of the setting image GC1.

In a state in which the setting image GC1 c is displayed on the touch panel 16, the computer 1 changes the setting image GC1 to be displayed on the touch panel 16 from the setting image GC1 c to the setting image GC1 d by receiving an operation from the user for moving the marker MG20 from a position of the point DG20 to a position of a point DG22. The setting image GC1 d is similar to the setting image GC1 c except that a position at which the marker MG20 is displayed is a position corresponding to the position of the point DG22.

For example, when the user checks the preview image GV and determines that the image GG1 is not appropriately deformed, the user can re-deform the image GG1 by executing at least one of designating a point DG substitutable for the point DG designated on the image GG1 and designating a point DP substitutable for the point DP designated on the captured image GP1.

When designating the point DG substitutable for the point DG designated on the image GG1, for example, the user moves the marker MG by dragging the marker MG corresponding to the designated point DG and dropping the marker MG at a target position. A cross symbol of the moved marker MG indicates a position of the point DG substitute. That is, the user moves the marker MG corresponding to the designated point DG, and designates the point DG indicated by the moved marker MG as the point DG substitute of the designated point DG. The computer 1 changes the point DG corresponding to the moved marker MG by receiving an operation from the user who moves the marker MG. Further, the computer 1 updates the correspondence relationship between the point DP and the point DG as the correspondence relationship between the marker MG and the point DG changes.

When designating the point DP substitutable for the point DP designated on the captured image GP1, for example, the user moves the marker MP by dragging the marker MP corresponding to the designated point DP, and dropping the marker MP at a target position. A cross symbol of the moved marker MP indicates a position of the point DP substitute. That is, the user moves the marker MP corresponding to the designated point DP, and designates the point DP indicated by the moved marker MP as the point DP substitute for the designated point DP. The computer 1 changes the point DP corresponding to the moved marker MP by receiving an operation from the user who moves the marker MP. Further, the computer 1 updates the correspondence relationship between the point DG and the point DP as the correspondence relationship between the marker MP and the point DP changes.

FIG. 20 is a schematic diagram showing the image GG6. Conversion equations for deforming the image GG1 into the image GG6 are generated based on a correspondence relationship between the points DG1 to DG26 and the points DP1 to DP26.

The computer 1 generates the preview image GV5 by combining the image GG6 and the captured image GP1 after generating the image GG6 by deforming the image GG1. The computer 1 displays the preview image GV5 in the region R3.

FIG. 21 is an illustrative diagram showing the setting image GC11. The setting image GC11 is an aspect of the setting image GC1.

In a state in which the setting image GC1 k is displayed on the touch panel 16, the computer 1 changes the setting image GC1 to be displayed on the touch panel 16 from the setting image GC1 k to the setting image GC11 by receiving an operation from the user who cancels designation of the point DG20 on the image GG1 or the point DP20 on the captured image GP1. The setting image GC11 is similar to the setting image GC1 k except that the marker MG20 is not displayed and that the marker MP20 is not displayed.

For example, when the user checks the preview image GV and determines that the image GG1 is not appropriately deformed, the user can re-deform the image GG1 by canceling the designation of the point DG designated on the image GG1 or the point DP designated on the captured image GP1.

When canceling the designation of the point DG designated on the image GG1, for example, the user performs an operation of erasing the marker MG corresponding to the designated point DG. The computer 1 cancels the designation of the point DG corresponding to the marker MG by receiving an operation from the user who erases the marker MG. The operation of erasing the marker MG may be, for example, an operation of double-tapping the marker MG to be erased, an operation of long-pressing the marker MG to be erased for a predetermined time or more, or the like.

When the designation of the point DP designated on the captured image GP1 is canceled, for example, the user performs an operation of erasing the marker MP corresponding to the designated point DP. The computer 1 cancels the designation of the point DP corresponding to the marker MP by receiving an operation from the user who erases the marker MP. The operation of erasing the marker MP may be, for example, an operation of double-tapping the marker MP to be erased, an operation of long-pressing the marker MP to be erased for a predetermined time or more, or the like.

In the embodiment, it is assumed that when one of the marker MG and the marker MP in the correspondence relationship is erased, the other of the marker MG and the marker MP is also erased. That is, when the designation of one of the point DG and the point DP in the correspondence relationship is canceled, the designation of the other of the point DG and the point DP is also canceled.

The user performs an operation of erasing the marker MG20 or the marker MP20 displayed on the touch panel 16. The computer 1 cancels the designation of the point DG20 and the point DP20 by receiving an operation from the user who erases the marker MG20 or the marker MP20.

In a state in which the setting image GC11 is displayed on the touch panel 16, the computer 1 changes the setting image GC1 to be displayed on the touch panel 16 from the setting image GC11 to the setting image GC1 m by receiving an operation from the user who touches the button B1. The setting image GC1 m is similar to the setting image GC11 except that the preview image GV6 instead of the preview image GV5 is displayed in the region R3.

The computer 1 deforms the image GG1 into the image GG7 by receiving an operation from the user who touches the button B1 on the setting image GC11. FIG. 23 is a schematic diagram showing the image GG7.

In a state in which the setting image GC1 k is displayed on the touch panel 16, the computer 1 changes the setting image GC1 to be displayed on the touch panel 16 from the setting image GC1 k to the setting image GC1 n by receiving an operation from the user who cancels the designation of the point DG26 on the image GG1 or the point DP26 on the captured image GP1. The setting image GC1 n is similar to the setting image GC1 k except that the marker MG26 is not displayed and that the marker MP26 is not displayed.

The user performs an operation of erasing the marker MG26 or the marker MP26 displayed on the touch panel 16. The computer 1 cancels the designation of the point DG26 and the point DP26 by receiving an operation from the user who erases the marker MG26 or the marker MP26.

In the embodiment, the operation of canceling the designation of the point DG26 or the point DP26 may be referred to as a “ninth operation”.

FIG. 25 is an illustrative diagram showing the setting image GC1 o. The setting image GC1 o is an aspect of the setting image GC1.

The computer 1 deforms the image GG1 into the image GG8 by receiving an operation from the user who touches the button B1 on the setting image GC1 n. FIG. 26 is a schematic diagram showing the image GG8. Conversion equations for deforming the image GG1 into the image GG8 are generated based on a correspondence relationship between the points DG1 to DG25 and the points DP1 to DP25.

The computer 1 generates the preview image GV7 by combining the image GG8 and the captured image GP1 after generating the image GG8 by deforming the image GG1. The computer 1 displays the preview image GV7 in the region R3.

FIG. 27 is a schematic diagram showing a mask image GM1. The mask image GM1 is a black-and-white binary image generated based on the captured image GP1. The computer 1 combines a deformed image obtained by deforming the image GG1 and the mask image GM1 using an arithmetic process such as addition, subtraction, multiplication, or division, so that an image including a part of the deformed image can be generated. In the embodiment, the image including a part of the deformed image may be referred to as a “partially deformed image”. In other words, the partially deformed image is an image in which a part of the deformed image is extracted based on the mask image GM1. In the embodiment, a case is assumed in which the computer 1 generates the partially deformed image along with the generation of the deformed image. Further, a case is assumed in which the computer 1 generates the preview image GV including the partially deformed image along with the generation of the preview image GV including the deformed image.

The setting image GC1 p is similar to the setting image GC1 c except that the preview image GV8 instead of the preview image GV1 is displayed in the region R3.

The button B2 is a button for the user to instruct the computer 1 to switch between displaying the preview image GV including the deformed image and displaying the preview image GV including the partially deformed image on the touch panel 16. The user instructs the computer 1 to switch the preview image GV by touching the button B2 displayed on the touch panel 16. In other words, the operation of touching the button B2 is an operation of designating whether the preview image GV displayed in the region R3 includes the deformed image or the partially deformed image. The computer 1 switches between displaying the preview image GV1 including the image GG2 that is the deformed image and displaying the preview image GV8 including the image GG9 that is the partially deformed image on the touch panel 16 according to an operation from the user who touches the button B2 on the setting image GC1 c.

FIG. 29 is a schematic diagram showing the image GG9. The image GG9 is generated by combining the image GG2 and the mask image GM1.

In the embodiment, the operation of designating whether the preview image GV includes the deformed image or the partially deformed image by touching the button B2 may be referred to as a “tenth operation”.

When the user checks the preview image GV and determines that the image GG1 is appropriately deformed, the user can end the process related to the deformation of the image GG1 by touching the button B3 displayed on the touch panel 16. The button B3 is a button for the user to instruct the computer 1 to complete the deformation process of the image GG1. The computer 1 completes the process related to the deformation of the image GG1 by receiving an operation from the user who touches the button B3 on the setting image GC1. Further, the computer 1 converts the deformed image such that the generated deformed image is displayed in a predetermined range in the projection region RS and on the torso 3. The computer 1 outputs the converted deformed image to the projector 7. The projector 7 displays the projection image GS including the deformed image by projecting projection light corresponding to the converted deformed image onto the projection region RS and the torso 3.

1.3. Configuration and Functions of Computer

Hereinafter, a configuration and functions of the computer 1 according to the first embodiment will be described with reference to FIGS. 30 and 31 .

FIG. 30 is a block diagram showing the configuration of the computer 1 according to the first embodiment. The computer 1 includes a storage device 10 that stores various pieces of information, a process device 12 that controls an operation of the computer 1, a communication device 14 that communicates with the camera 5, the projector 7, an external storage device, the external server, or the like, and the touch panel 16 that displays the setting image GC1 and that receives an operation from the user. The process device 12 has functions serving as an acquirer 120, a display controller 121, an outputter 122, and an image editor 130. Further, the image editor 130 has functions serving as an input manager 131, an image deformer 132, a preview generator 133, and a conversion equation generator 134. The touch panel 16 includes a displayer 160 and an inputter 161.

The storage device 10 includes, for example, a volatile memory such as a RAM and a non-volatile memory such as a ROM. Here, the RAM is an abbreviation for a random access memory. Further, the ROM is an abbreviation for a read only memory.

FIG. 31 is a block diagram showing a configuration of the storage device 10 according to the first embodiment. The non-volatile memory provided in the storage device 10 stores a program 100 defining the operation of the computer 1, image data 101 representing the image GG1, captured image data 102 representing the captured image GP1, mask image data 103 representing the mask image GM1, setting image data 104 representing the setting image GC1, deformed image data 105 representing the deformed image and the partially deformed image, preview image data 106 representing the preview image GV, input information 107 representing content of an operation received from the user, and conversion equation information 110 representing conversion equations used when deforming an image. The input information 107 includes information on a correspondence relationship between the point DG and the point DP. The conversion equation information 110 includes a deformation table 111 and an output table 112. The deformation table 111 represents the conversion equations for deforming the image GG1 into the deformed image. The output table 112 represents a conversion equation for converting the deformed image such that the deformed image included in the projection image GS is displayed in the predetermined range in the projection region RS and on the torso 3.

The output table 112 is generated based on a plurality of captured images acquired by the camera 5 capturing a plurality of black-and-white pattern images displayed by the projector 7 projecting the projection light onto the projection region RS and the torso 3. Different pattern images are recorded in the plurality of captured images. The number of the pattern images displayed by the projector 7 is determined based on resolution (specifically, the number of digits when the resolution is expressed in binary) of an optical modulator such as a liquid crystal panel provided in the projector 7. For example, when the projector 7 includes the liquid crystal panel and the resolution of the liquid crystal panel is 120×90, since each of “120” and “90” is expressed in a 7-digit binary, seven images for expressing coordinates in a horizontal direction and seven images for expressing coordinates in a vertical direction are required. Further, in order to prevent a decrease in imaging accuracy due to an influence of disturbance light such as illumination, it is preferable to use complementary patterns in which black and white of the pattern image is reversed in combination. That is, when the resolution of the liquid crystal panel provided in the projector 7 is 120×90, the output table 112 is generated based on twenty-eight captured images obtained by capturing a total of twenty-eight pattern images. The color arrangement of the pattern image is not limited to the black and white, and may be, for example, two colors including red and green. It is preferable to use two colors having high contrast as the pattern image.

The volatile memory provided in the storage device 10 is used by the process device 12 as a work area when executing the program 100.

A part or all of the storage device 10 may be provided in the external storage device, the external server, or the like. Further, a part or all of the various pieces of information stored in the storage device 10 may be stored in the storage device 10 in advance, or may be acquired from the external storage device, the external server, or the like.

The process device 12 includes one or more CPUs. However, the process device 12 may include a programmable logic device such as an FPGA instead of the CPU or in addition to the CPU. Here, the CPU is an abbreviation for a central processing unit, and the FPGA is an abbreviation for a field-programmable gate array.

The process device 12 functions as the acquirer 120, the display controller 121, the outputter 122, and the image editor 130 shown in FIG. 30 by the CPU or the like provided in the process device 12 executing the program 100 and operating according to the program 100.

The acquirer 120 controls the communication device 14 to acquire the various pieces of information from an external terminal such as the camera 5, the projector 7, the external storage device, or the external server communicably connected to the computer 1. Further, the acquirer 120 causes the storage device 10 to store the acquired various pieces of information. In the embodiment, the acquirer 120 acquires the image data 101, the captured image data 102, and the mask image data 103. The acquirer 120 causes the storage device 10 to store the acquired image data 101, captured image data 102, and mask image data 103.

In the embodiment, a case is assumed in which the image data 101 and the mask image data 103 are acquired from the external server (not shown), and the captured image data 102 is acquired from the camera 5. The external server acquires the captured image data 102 from the camera 5, and generates the mask image GM1 based on the captured image GP1 indicated by the captured image data 102.

The display controller 121 causes the setting image GC1 to be displayed by controlling the displayer 160 provided in the touch panel 16. Further, the display controller 121 causes the marker MG to be displayed in a manner of being superimposed on the image GG1 displayed in the region R1 of the setting image GC1 according to an operation from the user. Further, the display controller 121 causes the marker MP to be displayed in a manner of being superimposed on the captured image GP1 displayed in the region R2 of the setting image GC1 according to an operation from the user. Further, the display controller 121 causes the displayed marker MG and marker MP to be erased according to an operation from the user. Further, the display controller 121 causes the displayed marker MG and marker MP to be moved according to an operation from the user. That is, the display controller 121 causes the marker MG and the marker MP to be displayed at positions different from original positions according to an operation from the user. Further, the display controller 121 causes the preview image GV to be displayed in the region R3 of the setting image GC1 according to an operation from the user.

The image editor 130 executes various processes related to the deformation of the image GG1. Specifically, the image editor 130 functions as the input manager 131, the image deformer 132, the preview generator 133, and the conversion equation generator 134.

The input manager 131 manages the input information 107 representing content of an operation received from the user. Specifically, the input manager 131 acquires the input information 107 representing content of the operation received from the user by controlling the inputter 161 provided in the touch panel 16. Further, the input manager 131 causes the storage device 10 to store the acquired input information 107. Further, when the computer 1 receives a new input operation from the user, the input manager 131 updates the input information 107 stored in the storage device 10. Further, the input manager 131 performs various determinations related to the operation received from the user.

The conversion equation generator 134 generates the deformation table 111 based on a correspondence relationship between the one or more designated points DG and the one or more designated points DP. The deformation table 111 represents a plurality of conversion equations for deforming the image GG1 into the deformed image. Further, the conversion equation generator 134 causes the storage device 10 to store the generated deformation table 111.

The image deformer 132 deforms the image GG1 into the deformed image based on the conversion equations shown in the deformation table 111. Further, the image deformer 132 generates the partially deformed image by combining the deformed image and the mask image GM1. In other words, the image deformer 132 generates the deformed image data 105 representing the deformed image and the partially deformed image based on the deformation table 111, the image data 101 representing the image GG1, and the mask image data 103 representing the mask image GM1. Further, the image deformer 132 causes the storage device 10 to store the generated deformed image data 105.

The preview generator 133 generates the preview image GV obtained by combining the deformed image and the captured image GP1. Further, the preview generator 133 generates the preview image GV obtained by combining the partially deformed image and the captured image GP1. In other words, the preview generator 133 generates the preview image data 106 based on the deformed image data 105 representing the deformed image and the partially deformed image and the captured image data 102 representing the captured image GP1. Further, the preview generator 133 causes the storage device 10 to store the generated preview image data 106.

The outputter 122 converts the deformed image based on the output table 112. The outputter 122 outputs the converted deformed image to the projector 7 by controlling the communication device 14.

The communication device 14 includes, for example, an interface board including a connector and an interface circuit, and has a function of receiving the various pieces of information from the camera 5, the projector 7, the external storage device, the external server, or the like, and a function of transmitting the various pieces of information to the camera 5, the projector 7, the external storage device, the external server, or the like. In the embodiment, a case is assumed in which the communication device 14 is communicably connected to the camera 5, the projector 7, and the external server (not shown), and transmits and receives the various pieces of information. When transmitting and receiving the various pieces of information to and from the camera 5, the projector 7, the external server, or the like using wireless communication, the communication device 14 includes an antenna for performing wireless communication conforming to a predetermined wireless communication standard.

The touch panel 16 is a device in which the displayer 160 that displays an image and the inputter 161 that receives the input operation from the user are integrated. The displayer 160 includes, for example, a liquid crystal panel, an organic EL panel, or the like, and displays the setting image GC1 under control of the display controller 121. Here, the organic EL is an abbreviation for organic electro-luminescence. The inputter 161 includes, for example, a transparent sheet-shaped contact sensor. The inputter 161 covers the displayer 160. The inputter 161 detects a touched position using an electrostatic capacitance specified by an object in contact with the inputter 161 and the inputter 161, and outputs data indicating the detected touched position to the process device 12. The data indicating the touched position is stored in the storage device 10 as the input information 107.

When none of the input information 107 representing the content of the operation of canceling the designation of the point DG designated on the image GG1 or the point DP designated on the captured image GP1, the input information 107 representing the content of the operation of designating the point DG on the image GG1, the input information 107 representing the content of the operation of designating the point DP on the captured image GP1, the input information 107 representing the content of the operation of designating the point DG substitutable for the point DG designated on the image GG1, and the input information 107 representing the content of the operation of designating the point DP substitutable for the point DP designated on the captured image GP1 is acquired, that is, when the determination result of step S213 is YES, the input manager 131 advances the process to step S219. Further, when the input information 107 representing the content of the operation of canceling the designation of the point DG designated on the image GG1 or the point DP designated on the captured image GP1, the input information 107 representing the content of the operation of designating the point DG on the image GG1, the input information 107 representing the content of the operation of designating the point DP on the captured image GP1, the input information 107 representing the content of the operation of designating the point DG substitutable for the point DG designated on the image GG1, or the input information 107 representing the content of the operation of designating the point DP substitutable for the point DP designated on the captured image GP1 is acquired, that is, when the determination result of step S213 is NO, the input manager 131 advances the process to step S214.

In step S214, the input manager 131 determines whether the inputter 161 receives an operation from the user who touches the button B1. In other words, the input manager 131 determines whether the input information 107 representing content of an operation of instructing the deformation of the image GG1 is acquired. When the input information 107 representing the content of the operation of instructing the deformation of the image GG1 is acquired, that is, when the determination result of step S214 is YES, the input manager 131 advances the process to step S215. Further, when the input information 107 representing the content of the operation of instructing the deformation of the image GG1 is not acquired, that is, when the determination result of step S214 is NO, the input manager 131 advances the process to step S201.

In step S215, the input manager 131 refers to the input information 107, and determines whether the number of points DG and the number of points DP coincide with each other. When the number of points DG and the number of points DP coincide with each other, that is, when the determination result of step S215 is YES, the input manager 131 advances the process to step S216. Further, when the number of points DG and the number of points DP do not coincide with each other, that is, when the determination result of step S215 is NO, the input manager 131 advances the process to step S201.

When the number of point DG and the number of points DP do not coincide with each other, it is preferable that the display controller 121 causes a message that prompts the user to perform an operation for coinciding the number of points DG and the number of points DP with each other to be displayed.

In step S216, the conversion equation generator 134 generates the deformation table 111 based on the input information 107. Further, the conversion equation generator 134 causes the storage device 10 to store the generated deformation table 111.

In step S217, the image deformer 132 generates the deformed image data 105 representing the deformed image and the partially deformed image based on the deformation table 111, the image data 101 representing the image GG1, and the mask image data 103 representing the mask image GM1. Further, the image deformer 132 causes the storage device 10 to store the generated deformed image data 105.

In step S218, the preview generator 133 generates the preview image data 106 based on the deformed image data 105 representing the deformed image and the partially deformed image, and the captured image data 102 representing the captured image GP1. Further, the preview generator 133 causes the storage device 10 to store the generated preview image data 106.

After the process in step S218 is executed, the process device 12 ends the image deformation process shown in the flowchart in FIG. 33 .

In step S219, the image editor 130 determines whether the preview image GV is displayed on the displayer 160. When the preview image GV is displayed on the displayer 160, that is, when the determination result of step S219 is YES, the process device 12 including the image editor 130 ends the image deformation process shown in the flowchart in FIG. 33 . Further, when the preview image GV is not displayed on the displayer 160, that is, when the determination result of step S219 is NO, the image editor 130 advances the process to step S201.

After the image deformation process shown in the flowchart in FIG. 33 is ended, the process device 12 executes the process in step S105 shown in the flowchart in FIG. 32 .

When the preview image GV is not displayed on the displayer 160, that is, when the deformed image is not generated even once, the process device 12 repeats the image deformation process shown in FIG. 33 until the deformed image is generated. Further, when the determination in step S213 is YES and the preview image GV is displayed on the displayer 160, that is, when the deformed image is generated at least once, the process device 12 ends the image deformation process without generating a new deformed image.

In step S105, the display controller 121 causes the preview image GV to be displayed in the region R3 of the setting image GC1. When the preview image GV is displayed in the region R3 of the setting image GC1, the display controller 121 causes the preview image GV to be updated by controlling the displayer 160.

In step S106, the input manager 131 determines whether the inputter 161 receives an operation from the user who touches the button B2. In other words, the input manager 131 determines whether the input information 107 representing content of an operation of instructing switching of the preview image GV is acquired. When the input information 107 representing the content of the operation of instructing the switching of the preview image GV is acquired, that is, when the determination result of step S106 is YES, the input manager 131 advances the process to step S107. Further, when the input information 107 representing the content of the operation of instructing the switching of the preview image GV is not acquired, that is, when the determination result of step S106 is NO, the input manager 131 advances the process to step S108.

In step S107, the display controller 121 switches the preview image GV displayed in the region R3 of the setting image GC1. When the preview image GV including the deformed image is displayed on the displayer 160, the display controller 121 causes the preview image GV including the partially deformed image to be displayed by controlling the displayer 160. Further, when the preview image GV including the partially deformed image is displayed on the displayer 160, the display controller 121 causes the preview image GV including the deformed image to be displayed by controlling the displayer 160.

In step S108, the input manager 131 determines whether the inputter 161 receives an operation from the user who touches the button B3. In other words, the input manager 131 determines whether the input information 107 representing content of an operation of instructing completion of the image deformation process is acquired. When the input information 107 representing the content of the operation of instructing the completion of the image deformation process is acquired, that is, when the determination result of step S108 is YES, the input manager 131 advances the process to step S109. Further, when the input information 107 representing the content of the operation of instructing the completion of the image deformation process is not acquired, that is, when the determination result of step S108 is NO, the input manager 131 advances the process to step S200.

Until the determination in step S108 is YES, that is, until the operation of instructing the completion of the image deformation process is received, the process device 12 executes the image deformation process in step S200 again.

In step S109, the outputter 122 converts the deformed image based on the output table 112.

In step S110, the outputter 122 outputs the converted deformed image to the projector 7 by controlling the communication device 14.

After the process in step S110 is executed, the process device 12 ends the series of operations shown in the flowchart in FIG. 32 .

For example, the image GG1 may be deformed by receiving, from the user, an operation of designating a new point DG in addition to the point DG designated on the image GG1 and an operation of designating a new point DP in addition to the point DP designated on the captured image GP1. Accordingly, the user does not need an operation of touching the button B1 on the setting image.

The image GG6 is the deformed image.

That is, after the deformed image is generated, the computer according to the present modification can receive an operation of designating a new point DG in addition to the point DG designated on the image GG1 and an operation of designating a new point DP in addition to the point DP designated on the captured image GP1.

In the above-described embodiment and modifications, a case has been exemplified in which the display of the preview image GV including the deformed image and the display of the preview image GV including the partially deformed image are switched according to the operation from the user, but the present disclosure is not limited to such an aspect. For example, the preview image GV including the partially deformed image alone may be displayed. Accordingly, the user does not need an operation of touching the button B2 on the setting image.

As described above, in the image display method according to the fourth modification, the preview image GV is an image obtained by combining the partially deformed image obtained by extracting a part of a deformed image based on the mask image GM1 generated from the captured image GP1 and the captured image GP1.

For example, an arrow indicating a position of a point may be included instead of using the cross symbol. In addition, a symbol or a picture that can clearly indicate a position of a point may be included.

Further, for example, instead of using the number, a character such as “A”, “B”, “C”, and “D”, or “α”, “β”, “γ”, and “δ” may be included. Further, both the number and the character such as “No. 1” and “No. 20” may be included. The number is not limited to an Arabic number, and may be, for example, a Roman number.

The marker MG and the marker MP may be displayed in colors different from each other. For example, the marker MG may be displayed in blue, and the marker MP may be displayed in red.
